Serial No. 581,390.

To all whom it may concern:

Be it known that I, GEORGE B. Knrovnn, a citizen of the United States,residing at Uniontown, in the county of Fayette and State ofPennsylvania, have invented certain new and useful Improvements inRoofingBrackets, of which the following is a specification.

My invention relates to an adjustable bracket that may be used inshingling or slat-ing roofs, or in performing any work or repairs thatmay be necessary on the roof of a house in the course of construction oralready'completed, for the purpose of supporting the end of a scaffold,and is adjustable, to be used with equal efiect upon a roof of anyinclination.

The object of my invention is to provide an inexpensive, strong, light,and portable bracket of few parts for carpenters, slaters and others,that can be at once adjusted in place to hold the scaffolding, therebysaving the time required in ordinary cases to construct the same.

A further object is to provide a strap which is adapted to be removablyconnected to a specially constructed hitching plate and bracket frame,so that said strap can be easily inserted, or removed from the plate orbracket, after the slate or shingles are in place.

My invention consists of features of con struction and relativearrangementsof the several parts which will be hereinafter more clearlydescribed and particularly pointed out in the appended claims.

Referring to the accompanying drawings, in which the several parts areindicated by the same reference characters in the several figures:Figure 1, is a longitudinal sectional view of my invention; Fig. 2, isan isometric projection of the fastening plate, strap and bracketconnected together; Fig. 3, is a longitudinal section of the bracket inits folded position; Fig. 4, is a plan View of the fastening plate.

Referring to Figs. 1 to 4, my invention is provided with a-bracketframe, having a bottom section 2, end walls 3, 3, and side walls 4, 4.To the inside of the side walls 4, 4, is pivoted at 5, a U-shapedsupport 6, within which is hinged at 7, the legs 8, 8, suitably andpreferably connected by curved pieces 9, 9, as shown in Fig. 2. The freeends of the legs 8, 8, are provided with circular notches 10, adapted toengage the different parallel rods 11, 11, secured on the inside at oneend of the bracket frame. At the free end of the support 6, is rigidlyconnected an upwardly projecting extension 12, the function of whichwill be hereinafter fully explained. At the other end of the bracketframe is secured a plate 13, slightly above the bottom 2, and providedwith four V-shaped slits or openings 14, 14, to be engaged by one end ofa strap 15, passing through an opening 20, in the end wall 3 and abovethe plate 13, said strap having tongues 16, at one end adapted to passinto the slits 14 and firmly locked therein by an adjustable stop orcatch 17, held in any posi tion by means of a slot 18, and bolt,provided with a thumb nut 19.

18 is a holding plate having V-shaped slits 14, and suitable nailopenings 21, by which it may be securely fastened to a roof in such amanner as to receive and firmly engage the upper end of the strap 15,provided with similarly arranged tongues 16, as those engaging the slits14, of the bracket frame.

From the foregoing description, it will readily be seen that afterplates 13, have been properly spaced and secured to the roof to beshingled or slated, one simply hooks or fastens at one end two or morestraps 15, to as many plates 13, and at the other end of each strap issimilary secured a bracket frame by means of the adjustable catch 17.The support 6, of each frame is elevated so that it is in a horizontalplane and held in such position by means of the legs '8, 8, engaging bymeans of notches 10, the proper rod or rim 11, as shown in Figs. 1 and2, and thus adapting said bracket to accommodate itself to all roofinclinations as shown for example in dotted lines in Fig. 1.

The scaffolding or platform sections 22, see Fig. 1 connecting theseveral bracket supports are firmly held upon the supports 6, by meansof bent projections 12. When it is desired to remove the bracket fromthe roof, all that is necessary is to unfasten the bracket support fromone end of the strap 15, by unlocking the catch 17 which permitsunlocking the tongues 16, 16, from the slits 14, 14, and slipping theend of straps 15, through the opening 20. After the bracket support isdetached from one end of the strap 15, the upper end of said strap canbe easily and quickly detached from the holding plate 13, by an upwardmovement which removes from engagement the tongues 16 from the slits 14,in plate 13. The bracket support can be readily reduced to a compactform as indicated in Fig. 3, by folding the legs 8, 8, into the plane ofthe support 6.

What I claim is:

1. A roof bracket comprising a bottom section having slits and adaptedto rest upon the roof, an independent plate having slits and adapted tobe attached to the roof, a strap having tongues on each of its endsremovably engaging the slits of the bottom section and plate, a supportpivotally connected to the bottom section, and means for holding thesupport at various angular positions with respect to the bottom section.

2. A roof bracket comprising a bottom section having slits and adaptedto rest upon the roof, an independent plate having slits and adapted tobe attached to the roof, a strap having tongues on each of its endsremovably engaging the slits of the bottom section and plate, a supportpivotally connected to the bottom section, means on said support forfastening a platform, and means for holding the support at variousangular positions with respect to the bottom section.

3. A roof bracket comprising a bottom section adapted to rest upon theroof and having a false bottom provided with slits, an independent platehaving slits and adapted to be attached to the roof, a strap havingtongues on each of its ends removably engaging the slits of the falsebottom section and plate, a support pivotally connected to the bottomsection, and means for holding the support at various angular positionswith respect to the bottom section.

4:. A roof bracket comprising a rectangular bottom section adapted torest upon the roof and having an opening in one of its ends and slits onits bottom, an independent plate having slits and adapted to be attachedto the roof, a strap having tongues on each of its ends removablyengaging the slits of the bottom section and plate, said strap passingthrough the opening of the bottom section, a support pivotally connectedto the bottom section, and means for holding the support at variousangular positions with respect to the bottom section.

In testimony whereof I affix my signature in presence of two witnesses.
